I've climbed Little T 3 times, twice via the low crossing of the Cowlitz glacier at 6200' from Cowlitz Rocks saddle and up the Whitman (see Amar's trip reports for a description), once from the Fryingpan. Yesterday 2 friends and I tried to follow the "standard" climbing route described in the Volken book and got completely skunked and a bit scared trying to navigate heavily crevassed terrain on the Cowlitz. The 8600' contour described in the book is definitely only a general guideline. We followed some tracks which looked like they could quickly scoot us past a looming serac to easier terrain. Alas, there we were perched under the serac and blocked by a gaping slot. We boogied out of there, dropped some gear, and had a nice ski of the Paradise glacier on slightly over-ripe corn at 9 am.
Save yourself the trouble and take Amar's choice route if going from Paradise!
